x11-wm/xpra installs the /usr/lib/tmpfiles.d/xpra.conf file, which grants rwx rights of /var/run/xpra to the xpra user group, however this group is not created by the ebuild. OpenRC prints the following warning during boot: tmpfiles.setup | * checkpath: owner `0:xpra' not found
This bug was invalid. It only affected my own version bump to xpra 0.16.0. The tmpfile was not present in the 0.15 releases. Sorry for the noise.
Could you re-open this bug? The 0.16.2 ebuild in tree is affected by exactly this.
Sorry, I didn't check this file or reboot my system. commit 4367652caa27ce34983e973d39f8d750f3077e2e Author: Michael Weber <xmw@gentoo.org> Date: Thu Feb 25 15:50:57 2016 +0100 x11-wm/xpra: Revbump to add xpra system group (bug 572270, thanks Fabian Henze and Florian Schmaus).
